Abstract: 352,982. Setting projectile fuzes. NAAMLOOZE VENNOOTSCHAP HOLLANDSCHE INDUSTRIE-EN HANDELMAATSCHAPPIJ, 10, Javastraat, The Hague. Feb. 13, 1930, No. 4902. Convention date, Dec. 3, 1929. [Classes 9 (i) and 92 (ii).] An apparatus for setting projectile fuzes is provided with a seat e, Fig. 1, which under the weight of a projectile G sinks in a socket d and is at the same time rotated by a screw-thread e<1>. When the seat comes to bear on a disc g, it is free from the screw-threads but continues to rotate on ball bearings k<1> until spring plungers b, b<1> snap into the notches of the projectile and fuze rings respectively. The plunger b is on the socket d, and when the projectile is inserted in the apparatus is wedged into a hole c in the casing G<1> until released as explained above. After this release, the socket d slides down the casing, while a timing member d<1> carrying the plunger b<1> is rotated by a fixed nut h<1> until arrested by a stop m to which it becomes locked by a catch b<5> wedged out by a bar l depressed by a plunger b<3> wedged in by the socket d. The stop m is adjusted along a scale T by a screwspindle O rotated through gearing S by a handle n, Fig. 5, which also operates pointers q<1>, t<1> to follow indications received from a distance ; or the distant control is made to operate the spindle O directly. The time setting can be varied so long as the projectile is in the apparatus. When the projectile is removed, various springs F1, F2 .. return the various parts to the normal position. The removal of the projectile may operate a lever p to start a clockwork, which fires the gun after a predetermined time, or the pointer i of which comes opposite a mark k to indicate when the gun should be fired.

Title: Improvements in treatment process for altering the composition and properties of hypereutectic crude irons and irons obtained thereby
IPC: C21C1/00
Filed: 1950-03-02
Abstract: In a process for increasing the silicon content of crude hypereutectic iron, the molten hypereutectic iron is subjected to the action of a highly silicous slag, the silica content of which is reduced by the carbon and iron in the bath and/or by the addition of other reducing agents.  The slag should not contain more than 1 per cent of iron and manganese oxides and may contain coke or calcium carbide as reducing agent.  The slag, containing over 60 per cent of silica may be held in the molten state in a ladle and the crude iron added thereto.  Iron of the composition C-4.2 per cent, Si-0.38 per cent, Mn-0.7 per cent after treatment with a slag containing 64 per cent silica resulted in an iron of the composition C-3.98 per cent, Si-1.95 per cent, Mn 0.51 per cent.

To prevent an actuator becoming locked on in an extreme position due to high emergency reservoir pressure a braking system including an actuator 10 having spring applied, fluid pressure released brake locking means, an emergency reservoir 40 and an emergency line 34 for controlling a relay valve 38 to deliver pressure from the reservoir to the actuator upon venting of the emergency line, is provided with a flow retarder fitted to connect the actuator and reservoir to atmosphere upon venting of the emergency line and means for feeding back to the port 14 of the lock release means the pressure existing in the conduit between the actuator and the flow retarder. The retarder comprises a first choke 52, a second, and smaller, choke 62 being also provided. Should the emergency line 34 be vented full reservoir pressure is applied to actuator parts 12 and the fall in pressure at the lock ports 14 which would normally occur is delayed by the choke 52. The reservoir and actuator pressure also falls as air bleeds through chokes 62, 52 to atmosphere through line 34. The pressure between the chokes is fed back through line 54 to hold released the brake locking means until the reservoir and the actuator pressures have dropped to a suitable value. The locks are then applied and remain on.
